Abstract

The invention provides an isolator reverse power withstand test system and method, comprising: after the original single-carrier signal sent by the signal source is amplified by a microwave power amplifier, it is provided to the first power meter and vacuum through the first dual-directional coupler tank; the first power meter measures the power value of the original single-carrier signal to form the first power value; the isolator is placed in the vacuum tank; the original single-carrier signal is provided to the second forward coupler through the isolator, through the second forward The coupler is provided to the short-circuit block; the original single-carrier signal enters the short-circuit block for delay and reverse transmission to form a reverse carrier signal, and the reverse carrier signal passes through the second forward coupler and isolator before being provided to the first dual-directional Coupler, and provide to the third power meter; The third power meter measures the power value of the reverse carrier signal to form the third power value; Calculate the composite signal power value according to the first power value; According to the composite signal power value and the third power value to get reverse isolation.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to an isolator reverse power withstand test system and method. Background technique [0002] At present, with the improvement of remote sensing observation capabilities, remote sensing satellites are showing a rapid development momentum. The payloads carried by remote sensing satellites are gradually developing into multiple methods and diversification. Hyperspectral and multispectral payloads bring higher-precision and higher-resolution image effects, and at the same time generate more and more payload data. In order to meet the high-speed downlink requirements of massive data from low-orbit remote sensing satellites, it is necessary to increase the satellite-to-ground data transmission rate. [0003] In a certain satellite model, calculating the effective data and transit time generated by an optical payload every day, it can be concluded that the satellite-ground data rate is...
